Siemens has completed an investigation of the reported event.The root cause was determined to be a hardware error.The table up button of the table control module (tcm) of the x-ray system was defective, which meant that the control of the table upward movement was constantly activated.This was detected by the system and, for safety reasons, all movement control via tcm was blocked by the system.This is a specified function that prevents uncontrolled movements of the table and represents a mitigation of the problem.Although this overrode the tcm of the system, it did not affect the movements initiated from the oem table.These continued to function because the trumpf oem table has its own control circuit.After replacing the affected tcm, the system again functioned as specified.The error has not been reported again and a possible general fault that would require corrective action of the installed base could not be determined by the investigation.After detailed investigation, the incident is not classified as a reportable event as neither serious injury, death nor an unexpected, prolonged hospitalization of the patient or any other person occurred or could be expected.
